Closing down a forum

I realise that the best way to delete a forum, say an invisionfree, would be to link one of the administrators to a fake login and then steal their password. What are the options for a ***rd that is now inactive but still has thousands of posts & the admin log ins a couple times a year for whatever reason? I would presume there are no options to delete this ***rd?

ive heard invisionfree is pretty much impossible to crack even with an active admin - anyone got anything?

This was covered a few years ago. http://www.all-nettools.com/forum/showthread.php?26**-Hacking-*certain*-invisionfree-***rds

Your best bet now is googling for invisionfree exploits.
